Abstract

Pyrogent fremstilt silika behandlet med sølv eller sølvoksid fremstilles ved å tilføre en aerosol i en flamme slik som benyttes for fremstillingen av pyrogent silika, å blande aerosolen homogent med gassblandingen før reaksjonen, deretter å reagere aerosolen/gassblandingen i en flamme og å separere de pyrogene silikaene behandlet med sølv eller sølvoksid som er oppnådd fra gasstrømmen på kjent måte. Det pyrogene silika behandlet med sølv eller sølvoksid ved hjelp av en aerosol kan anvendes som et baktericid fyllstoff.
